• State-of-the-Art
• The NEWSKY Approach
• Benefits and Challenges
• Project Overview

State-of-the-Art

• Current ATM communications systems in Europe will
  be completely overloaded within the next 15
  years, even if
• 8,33 kHz program is extended
• VDL Mode 2 is completely deployed (Link 2000,
  Cascade)
• For passenger communications (APC) a strong
  market demand on high-rate data transmissions is
  still expected
• Covered mainly by satellite communications
• Re-use of satellite capacity for ATM seems
  possible if technical challenges (security,
  integrity, QoS) can be solved
• Change of paradigms in aeronautical
  communications is expected
• Less ATM voice, more ATM data link communication
• Integration of ATM and APC into one framework

State-of-the-Art

• Requirements from ACARE SRA 2020
• Three times more aircraft traffic en-route
• Three times increased airport capacity
• Nine times improved security
• Transparent ATM system
• Actions currently undertaken
• Europe (EC Projects) ANASTASIA, B-VHF,
• ICAO ACP activities
• FCS and FCI jointly developed by FAA and
  Eurocontrol
• Expectation Several aeronautical communications
  system for different application areas
• Missing Overall approach, integrated network

The NEWSKY Approach

• Networking the Sky Development of a global,
  heterogeneous communications network for
  aeronautical communications
• Integration of different communications systems,
  i.e. ground-based ATM, satellite-based ATM, ATM
  within airports (A-SMGCS), and ATM between
  aircraft (ad-hoc network)
• Integration of different applications and
  services ranging from ATC/ATM over AOC and AAC
  to APC
• Ensuring that safety critical applications and
  services are always served in time with the
  required Quality of Service (QoS)
• Ensuring network security
• Goal Enable aircraft to be included in CDM and
  SWIM
• Similar research in the U.S. on network enabled
  operation
• NEWSKY enabler for the flexible airborne
  infrastructure!?!

The NEWSKY Approach

• Detailed NEWSKY work program
• Develop framework for ATM network transformation
• Identify relevant application scenarios and
  service requirements
• Develop framework for NEWSKY network concept and
  architecture
• Design and evaluate NEWSKY integrated airborne
  network
• Validate NEWSKY integrated airborne network
  design
• Validation using simulations
• Validation in laboratory trials
• Overall NEWSKY goalIntegration of both different
  communications systems and different applications
  into a global, heterogeneous network

Benefits and Challenges

• Benefits of NEWSKY approach
• Increased redundancy, thus, increased
  availability and reliability
• Increased coverage of overall system
• Globally optimized network performance by using
  the right communication link technology at the
  right place and time
• Improved performance and system capacity
• Increased overall efficiency
• ATM system completely transparent to end
  users(pilots and controllers)
• Modular system concept which enables more
  simpleintroduction of new technologies
• Efficient and flexible utilization of the
  overallaeronautical frequency spectrum
